private XExpression parseScriptIntoXTextEObject(String scriptAsString) throws ScriptParsingException {
    XtextResourceSet resourceSet = getResourceSet();
    // IS-A XtextResource
    Resource resource = resourceSet.createResource(computeUnusedUri(resourceSet));

    } catch (IOException e) {
        throw new ScriptParsingException("Unexpected IOException; from close() of a String-based ByteArrayInputStream, no real I/O; how is that possible???", scriptAsString, e);
    }
    List<Diagnostic> errors = resource.getErrors();
    if (errors.size() != 0) {
        throw new ScriptParsingException("Failed to parse expression (due to managed SyntaxError/s)", scriptAsString).addDiagnosticErrors(errors);
    }
    EList<EObject> contents = resource.getContents();
